T0 VALL WHOM IT MAY -GON CERN: i

Be it known that I, ALANsmr- H. MsnnIxAK, f Nerv Britain, county of Hsrtford,`and State of Connecticut', have invented certain new and useful Improvements in Adjustments of Press-'Spind1e; and to enable others skilled in the art togmake'and use the sauie, I -will proceed tdescribe its construction and operation by refer- Y ring to the drawings, in which the saine letters indicate like pn'rts in each of the' figures.

The nature of this invention cbnsistsin .the mode of adjusting the length of the Vs|r i u4dle,` .`iu orlto which a tool'or die issecured, in its relative'pos, ition to the work it hns to perform; or, in other words', it consists in so constructing the tool-stock or spindle. of n press, that the punch or die secured therein canvfh'o pickin-easily,

and accurately adjusted toany particular' point.

In the accompanying vdrav'ringsr- Figure 1 is a. sectional side view. Y Figure 2 is au end view.

Iand freely u ponfthe right and left-hand screw formed on the stock or spindle A At This sleeveV is also provided with' four slits, a, (suore orA lesen) in each end Ythereof, extending neer to the"7 'i collar C. It is also provided with right and left-hand screws upou its outside surface, and xt each end, 'wlril'ili is mide slightly tapering. 1 l f v -E E nre nuts, which are ttedclosely and work 'freely upon each end of .the sleeve BL These nuts are 01"'` may he made square or nut-form, and provided with sockets,'f, to receive an uctnnting-har. n

Thus it will be-seen that by loosening the nuts E, and turning the cellar G, the'stock'or ,spindlecan lie i i `eaisily and quickly adjusted with' the greatest degree of accuracy, aud'again firmly and securely tightened at v any desired point. y

I h'elieve 'I have thus' shown ,the nature, construction, and advantage ofthis invention, so as izo-enable other: i

skilled in the art Ineke and use the saine therefrom. WhstI claim, therefore, and desirc ,to secure by Letters Patent, is'

' The comhi'netionef the tool-stock or spindle A A with the sleeves B and ,and collar C, arranged und operating substantially as and for the `purpose described.
